摘要
为明确不同麦类种质资源对大麦黄矮病毒(Barley yellow dwarf viruses,BYDV)的抗性差异,于2015—2016年连续两年采用堆测法在田间人工接种鉴定了231份麦类种质资源的抗病性。结果表明,不同麦类种质资源对BYDV引起的黄矮病的抗性存在较大差异,2015—2016年,克群、加麻白芒麦、墨沙、绿见口和灰木头的平均病情指数分别为20.40、22.28、23.08、22.34和13.08,对黄矮病表现出较好的抗性;团结红壳麦-K、红矮子、定兴寨、旱地小麦、小红狼、榔头麦、峥白毛、金包银、红四楞、赤壳须麦及和穗板麦的平均病情指数分别为74.68、71.62、70.36、68.44、65.17、64.74、63.29、60.97、55.78、56.42和53.21,均大于50.00,表现为高感;其余种质资源的平均病情指数在25.00~50.00之间,表现为感病。此外,长芒芒、冰糖色小麦、苏麦、红皮麦、小红穗和青兰麦初期表现感病,后期可恢复健康,有一定的耐病性。抗病性不同的麦类种质资源感染BYDV后,对产量的影响差异很大,其中抗病资源绿见口的产量损失率最低,为8.87%,耐病资源长芒芒、冰糖色小麦、苏麦、红皮麦、小红穗和青兰麦的产量损失率依次为16.90%、17.40%、15.04%、13.13%、18.94%和11.57%,而感病资源和穗板麦的产量损失率达43.57%。
To definite the resistance difference of wheat germplasm resources to Barley yellow dwarf viruses（BYDV）, 231 wheat germplasm resources were tested using artificially inoculated with viruliferous aphid Schizaphis graminum using hill plot technique on field in 2015 and 2016. The results showed that BYDV resistance were varied significantly among 231 wheat germplasm resources. The disease indexes of Kequn, Jiamabaimangmai, Mosha, Lüjiankou and Huimutou were 20.40, 22.28, 23.08, 22.34 and 13.08, respectively, showed resistance to BYDV in 2015—2016. In contrast, Tuanjiehongkemai-K,Hong＇aizi, Dingxingzai, Handixiaomai, Xiaohonglang, Langtoumai, Zhengbaimao, Jinbaoyin, Hongsileng, Chikexumai and Hesuibanmai of which the disease indexes were 74.68, 71.62, 70.36, 68.44, 65.17,64.74, 63.29, 60.97, 55.78, 56.42 and 53.21, respectively, for these wheat germplasm resources of which the disease indexes all was higher than 50.00, were considered to be highly susceptible to BYDV. The rest wheat germplasm resources with disease indexes ranging from 25.0 to 50.00 were susceptible to BYDV. Furthermore, six wheat germplasm resources, Changmangmang, Bingtangsexiaomai, Sumai, Hongpimai, Xiaohongsui and Qinglanmai, which showed susceptible to BYDV on early stage but alleviated or disappeared at grain-filling stage, these six wheat germplasm resources showed tolerance to BYDV.Significant difference was observed on yield loss when wheat germplasm resources contained different resistance were infected with BYDV. The yield loss of the germplasm resource, Lüjiankou was 8.87%,followed by tolerant varieties, Changmangmang, Bingtangsexiaomai, Sumai, Hongpimai, Xiaohongsui and Qinglanmai, with 16.90%, 17.40%, 15.04%, 13.13%, 18.94% and 11.57% yield loss, respectively,while susceptible variety Hesuibanmai showed the yield loss as high as 43.57%.
